The kid with the Huck Finn smile from Toms River, N.J., who led his team to the 1998 Little League World Series title, will play in his first All-Star Game Tuesday — Derek Jeter’s final All-Star Game.

On Monday night in the Home Run Derby at Target Field with his brother Charlie, 34, a sixth-round draft pick of the Marlins in 1999, pitching to him and his other brother Jeff, 31, leading the cheers, Todd made it all the way to the finals before losing to the mighty Yoenis Cespedes.

Yes, the Reds’ third baseman and his family are having a blast.

“To me, this is the pinnacle of where Todd wanted to go with baseball in his life,’’ Charlie Frazier Sr., Todd’s father, told The Post. “To make it to the All-Star Game and Home Run Derby, it’s hard to put into words, how a parent feels. It’s just numbing.

“You have to work hard and he’s done just that. There is no easy road.’’

The Family Frazier is here in force with parents Charlie Sr. and Joan, Charlie Jr. and Jeff, father-law Kevin Verdon and Todd’s wife, Jackie, and their 4-month-old baby boy Blake.

“Family comes first,’’ Todd, 28, said Monday as his family joined in all the festivities. “They will find a way to get into some trouble, that’s the Jersey in them. They’re walking around taking pictures and trying to get whatever they can in their backpacks.’’

“There will be parties all over the place in Toms River,’’ Charlie Sr. said. “Everybody is going to be at the beach bars. The town really supports him.’’

Just as in 1998, when Todd led Toms River East-American to the Little League World Series title, as he batted .600 with four home runs and in the title game went 4-for-4 and pitched the final two innings.

Charlie Jr., who played six seasons in the minors with the Marlins, said, “This is a dream come true for me and the whole family.’’

“In a way,’’ Todd said of the Home Run Derby, “this is Charlie’s day, too. He was the first one in the family drafted.’’

Charlie Sr. has been retired for three years after working 39 years in education, and was a vice principal his last 16 years.

“It was good, but I’m having a hell of a good time with this retirement stuff,’’ Charlie said with a laugh. Joan will retire within the next year. She is the attendance officer at Toms River South High School. Todd’s other brother Jeff made it to the majors with the Tigers in 2010. Charlie Jr. and Jeff are both teachers now.

“In 2010 up in Boston, Jeff hit one off the Green Monster, I’ll never forget that at-bat, and this year Todd hit one off the Monster,’’ Charlie Sr. said. “How many times you get the chance to see something like that?’’

Charlie Jr. and Jeff also run a successful Baseball Academy called Frazier Baseball.

“Todd has always had fun with the game,’’ his father said. “He’s genuine about everything he does. He’s dealt with the media for a long time and he’s pretty relaxed about it. The thing that really impresses me is his peers respect him and he has a great camaraderie with the rest of the league. He’s a players’ guy, they all like him. When he is on first base sometimes, I swear, he must miss some signals because he’s always talking to guys. He’s always positive, too.’’

Frazier was the same way at 12 years old.

The first time I came across him, he was leading his teammates onto the field, chanting, “Who Let The Dogs Out.’’

That was two years before the song became a hit.

What a ride it has been over the past 16 years. There was the trip to Yankee Stadium for that championship team, and Todd got to stand at shortstop with Derek Jeter.

“Something I’ll never forget,’’ Todd said. “He said, ‘Congratulations, how was it?’ I told him it was a lot of fun and he said ‘Good luck.’ ”

Now Frazier is appearing in his first All-Star Game — and Jeter’s last.

Charlie Sr. and Joan have three grandsons and a granddaughter. Down the road, there might be another generation of Fraziers playing baseball.

“Now that we have a girl,’’ the proud grandfather said, “I might have to start looking at softball and set her up on the tee and see what her swing looks like,. She is only three, but you never know.’’
